Michal, is there a testcase I can plug into kselftests to make sure we got this right (and don't regress)? We care a lot about memory hotplug working right.
As said in other email. The memory hotplug tends to work usually. It takes unexpected memory layouts which trigger corner cases. This makes testing really hard.
Can we do something with qemu? Is it flexible enough to hotplug memory at the right boundaries?
No idea. But I have tried to describe those layouts in the changelog so if somebody can come up with a way to reproduce them under kvm/qemu I would really appreciate that.
